如何使测试采用现有的 coin_id？

Question

我的代码

需要测试本身可以替代现有的coin_id，这样以后测试就不会掉下来，比如因为id=2[=12下的一个硬币被移除=]

class ModelTransactionTest(TestCase):
    @freeze_time(timezone.now())
    def test_auto_setting_date_if_field_empty(self):
        field = Transaction.objects.create(rubles_cost=1, purchase_price=1, amount=1, 
            dollars_cost=1, coin_id=2)
        self.assertEqual(timezone.now(), field.date)

Answer 1

您应该在测试中创建硬币实例

class ModelTransactionTest(TestCase):
    def setUp(self) -> None:
        super().setUp()
        self.coin = Coin.objects.create(kwargs required to create object)

    @freeze_time(timezone.now())
    def test_auto_setting_date_if_field_empty(self):
        field = Transaction.objects.create(rubles_cost=1, purchase_price=1, amount=1, 
            dollars_cost=1, coin=self.coin)
        self.assertEqual(timezone.now(), field.date)

如何使测试采用现有的 coin_id？
